Nā waiwai minerala a me ka hoʻolālā mineral
ʻO nā minerale e lawe ana i ka Titanium ka nui o ka ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, a me nā mea ʻē aʻe, i waena o ka ilmenite a me ka rutile ka mea nui o ka titanium smelting mineral.
ʻO ka molecular formula o ka ilmenite ʻo FeTiO3, ma ke ʻano he 52.66% o TiO2 a me 47.34% o FeO. He kila hina i ka ʻeleʻele ʻeleʻele, me ka paʻakikī Mohs o 5-6, ka mānoanoa o 4.72g/cm3, medium magnetism, conductor maikaʻi, a me ke ʻano maʻamau. Hoʻohui ʻia ka ʻike qualitative me ka magnesium a me ka manganese, a i ʻole i loko o nā inclusions hematite scaly maikaʻi.
ʻO ka molecular formula o rutile ʻo TiO2, loaʻa iā 60% Ti a me 40% O. He mineral ʻulaʻula brownish, i loaʻa pinepine i ka hui ʻana o ka hao, niobium, chromium, tantalum, tin, etc., me ka paʻakikī Mohs o 6, a me ka mānoanoa o 4.2 ~ 4.3g/cm3. Magnetism, conductivity maikaʻi, ʻeleʻele ʻeleʻele ke kiʻekiʻe ka ʻike hao, hana nui ʻia ka rutile ma nā wahi.
Nā kahua noi a me nā hōʻailona ʻenehana
ʻO Rutile a me ilmenite ka mea nui no ka hoʻoheheʻe ʻana i ka titanium metala, ka hana ʻana i ka titanium dioxide, nā koʻokoʻo welding, a me nā fluxes welding.

ʻenehana hana
ʻO ka maʻamau ilmenite a me rutile ore e hui pū ʻia me nā ʻano mineral ʻē aʻe, e like me ka magnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene Stones, etc. kaʻawale, kaʻawale uila a me ka lele.
Pōmaikaʻi gravity
Hoʻohana pinepine ʻia kēia ʻano hana no ka hoʻokaʻawale ʻana o ka mea hoʻokomo i loko o ka titanium a i ʻole nā mea nui i loko o ka titanium i ʻoki ʻia. ʻOi aku ka nui o ka nui o nā minerala me ka titanium ma mua o 4g/cm3. No laila, hiki ke hoʻoneʻe ʻia ka hapa nui o nā gangues me ka mānoanoa o lalo o 3g/cm3 e ka hoʻokaʻawale ʻana i ka gravity. Ka wehe ʻana i ka mineral. ʻO nā mea hana hoʻokaʻawale gravity ka jig, spiral concentrator, shaker, chute, etc.
Mākēneki hoʻokaʻawale
Hoʻohana nui ʻia ke ʻano hoʻokaʻawale magnetic i ke koho ʻana i nā minerala me ka titanium. Hiki iā mākou ke hoʻohana i ka hoʻokaʻawale magnetic nāwaliwali e hoʻokaʻawale i ka magnetite, a laila hoʻohana i ka hoʻokaʻawale magnetic ikaika e hoʻokaʻawale i ka ilmenite medium-magnetic. No ka laʻana, ʻoi aku ka nui o ka hao iron oxide a i ʻole No ka hao silicate, pono e hoʻohana ʻia ke ʻano hoʻokaʻawale ʻumekaumaha e wehe i nā haumia me kahi ʻumekaumaha liʻiliʻi. Ma ka ʻoihana, hoʻohana ʻia nā mea hoʻokaʻawale maloʻo maloʻo a me ka pulu.

Hoʻohana nui ia i ka ʻokoʻa o ka conductivity ma waena o nā minela like ʻole i ka titanium-containing coarse concentrate no ke koho ʻana, e like me ka hoʻokaʻawale ʻana o ka rutile, zircon, a me ka monazite. ʻO nā mea hoʻokaʻawale uila i hoʻohana ʻia he ʻano roller, ʻano pā, ʻano sieve plate a pēlā aku.

Hoʻohana nui ʻia ia e hoʻokaʻawale i ka titanium i loaʻa i ka ʻaila. Hoʻohana pinepine ʻia nā mea hoʻopiʻi flotation me ka sulfuric acid, ka aila kiʻekiʻe, ka ʻakika oleic, ka ʻaila diesel a me nā emulsifiers. ʻO nā ala e pōmaikaʻi ai, ʻo ia ka flotation maikaʻi o ka titanium a me ka flotation hoʻohuli o nā minerala gangue.
Pōmaikaʻi hui
No ka placerite me nā minelala e pili ana, hiki ke hoʻohana ʻia ka ʻokoʻa o ka susceptibility magnetic, density, conductivity, a floatability ma waena o nā minerala e hoʻokaʻawale i nā minela ma ke kaʻina hana "magnetic, heavy, electric, and float". No ka laʻana, ke kahakai. Loaʻa i ke one alluvial nā minerale e like me ka magnetite, ilmenite, rutile, zircon sand, monazite, ke one kai, etc. ʻO ka mua, ua hoʻokaʻawale ʻia ka magnetite e ka mānoanoa nāwaliwali, a laila hoʻokaʻawale ʻia ka ilmenite e ke apo kūpaʻa me ka ikaika waena. ʻO ke apo kiʻekiʻe kiʻekiʻe o ke apo kuʻekuʻe o nā huelo apo kuʻekuʻe e hoʻoneʻe i nā minerala hao hao ʻē aʻe, a laila hoʻokaʻawale ʻia ka ʻumekaumaha liʻiliʻi e ke ʻano hoʻokaʻawale gravity. No ke one kai, he rutile a me ke one zircon nā mineral koʻikoʻi. Hiki ke koho ʻia ka rutile me ka conductivity maikaʻi e ka hoʻokaʻawale uila, i mea e hoʻopau ai i ka hoʻokaʻawale kūpono o kēia ʻano mineral.
